Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 13/153,673, filed Jun. 6, 2011, incorporated by reference herein.

FIELD OF THE INVENTION

Embodiments of the invention generally relate to information technology, and, more particularly, to health management.

BACKGROUND OF THE INVENTION

The prevalence of lifestyle-related health problems poses a grand challenge to national health systems. For example, structured lifestyle intervention on controlling health risks can be effective, but the implementation of such user-centric plans can quickly drain out resources.
Dynamically forming wellness service ecosystems to offer personalized lifestyle intervention plans also exist. However, while existing providers keep expanding service choices to cover various user needs, there is still a long tail of demand unsatisfied, such as, for example, the ability to infer wellness needs and adjust interventions accordingly.
Additionally, existing approaches often provide a rigid system design that limits the reusability, composibility, and accessibility of the components. As a result, the existing systems do not facilitate individuals with self-assessment capabilities or control over an individual wellness management process. Also, existing approaches do not fully utilize risk models.

An exemplary method (which may be computer-implemented) for providing one or more user-centric wellness decision support services, according to one aspect of the invention, can include steps of providing an interface that facilitates selection of a risk assessment model of interest for a user and an action plan to trigger one or more follow-up action items, applying the selected model to assess the user's wellness risk level based on one or more user wellness records, and applying the selected action plan to trigger one or more relevant disease management and lifestyle interventions.
One or more embodiments of the invention or elements thereof can be implemented in the form of a computer product including a tangible computer readable storage medium with computer useable program code for performing the method steps indicated. Furthermore, one or more embodiments of the invention or elements thereof can be implemented in the form of an apparatus including a memory and at least one processor that is coupled to the memory and operative to perform exemplary method steps. Yet further, in another aspect, one or more embodiments of the invention or elements thereof can be implemented in the form of means for carrying out one or more of the method steps described herein; the means can include (i) hardware module(s), (ii) software module(s), or (iii) a combination of hardware and software modules; any of (i)-(iii) implement the specific techniques set forth herein, and the software modules are stored in a tangible computer-readable storage medium (or multiple such media).

DETAILED DESCRIPTION OF EMBODIMENTS

Principles of the invention include risk-driven wellness decision support services. As detailed herein, one way to help overcome “treatment inertia” (that is, the inclination of human beings to resist change) is to allow the users to perform self-assessment on wellness risks and find suitable life intervention plans accordingly. In one or more embodiments of the invention, the development of a wellness decision support tool involves at least the tasks of applying risk models to infer a person's wellness status, and, given the wellness risk assessment, following the wellness guidelines to select suitable lifestyle intervention plans.
Also, one or more embodiments of the invention include designing a wellness cloud that is a dynamic infrastructure pattern that follows service-oriented approaches to facilitate the collaboration among wellness service providers and independent software vendors (ISVs). On top of the wellness services can be provided to develop a configurable wellness decision service engine, where service providers, with permission from the user, can plug-in various wellness evidences to provide personalized services.
Additionally, one or more embodiments of the invention include components such as storage of a patient's health profile (for example, previous lab exam results), expert-provided guideline for health promotion (for example, exercise routines or dietary plans), connection to a specific brand of monitoring devices for direct download, and connection to clinical experience (for example, clinical visit calendar).
As described herein, a wellness decision support system uses a statistical engine to perform remote wellness knowledge application, and can also complement a patient similarity engine to perform collaborative filtering as the foundation of any personalization service.
As further detailed herein, one or more embodiments of the invention can include the following aspects. To address the challenge of wellness knowledge reusability, a knowledge manager is used that handles the publish/subscribe (pub/sub) mechanism of wellness knowledge (which can be stored in the international predictive model markup language (PMML) standard) and allows joint analysis, such that models can be applied on the fly to datasets of different parties. To address the challenge of wellness decision service accessibility and composibility, a user-configurable wellness decision services is used in which a user can specify the model and guideline of interest in the wellness knowledge repository and apply them on his or her own wellness records for assessment and action. Also, for the users/developers who are not domain experts, one or more embodiments can also include a configure-free module, which can interactively solicit user models (that is, wellness management goal and perceived importance of risk factors) from user input and select the most relevant action plans according to the learned user model.
Additionally, one or more embodiments of the invention can also include a platform that is equipped with connections to personal wellness record databases and analytics capabilities of bootstrapping the processing of personal wellness risk profiling from examples, saving users from the high entry barrier of manual input. Also, a context-awareness component can be include that integrates contextual information, which is collected from smart sensors (for example, activity type, location, social network status) and users in the loop to infer personal wellness status (that is, how the patient is). Further, a personalized continuous feedback loop mechanism can also be included that can update a current status and recommended services with respect to changes revealed in the monitoring context.
In one or more embodiments of the invention, parameters can be configured to include the types of health risk and the factors a user wants to control. The configured service can then analyze the risk factors underlying the selected types of risk models and compare their risk levels with the selected population group with which to compare. If no population group is selected, a subset of users who are the most similar to a particular user's wellness history can be selected for comparison.
FIG. 1 is a diagram illustrating risk-driven wellness decision support architecture, according to an embodiment of the present invention. By way of illustration, FIG. 1 depicts a user device 102, a data collection network 104, a personal wellness record (PWR) 106, a data request component 108, a knowledge manager component 110, a personal wellness decision support component 112, application components 114 and output components (for example, clinical decision support, risk stratification, personalization, etc.) 116.
As illustrated in FIG. 1, one or more embodiments of the invention include the feature of reusable domain knowledge. Domain experts or vendors can upload risk assessment models and follow-up action plans for others to use. Additionally, one or more embodiments of the invention include configuring a wellness decision service. As depicted in FIG. 1, users can select any given model from the repository to apply on their own wellness records for assessment.
One or more embodiments of the invention, as noted herein, can also include the feature of a configure-free module. For those who do not know which model or action plan to choose, service providers can invoke the configure-free module to solicit input from healthcare professionals and users so as to select suitable actions accordingly at the point of wellness care.
FIG. 2 is a diagram illustrating example steps for risk-driven wellness decision support, according to an embodiment of the present invention. By way of illustration, FIG. 2 depicts preprocessing steps 202, personal wellness risk profiling for healthcare professionals steps 204, visualization for joint decision making steps 206 and user model solicitation steps 208. Preprocessing steps 202 include establishing connection to PWR and pre-fetching relevant PWR data fields for analysis. Personal wellness risk profiling for healthcare professionals steps 204 include scanning PWR for relevant risk factors of each important risk to be watched (based, for example, on a physician's prescription), triggering relevant risk models (or guidelines) to estimate risk levels and the importance of each risk factor, performing a risk-benefit analysis and scoring the weights of factors to be monitored.
As also detailed in FIG. 2, visualization for joint decision making steps 206 include converting the wellness risk profile to visual objects, creating and exposing widgets that illustrate the profile from the last step, soliciting user-specified benefits of interventions, and composing a dashboard based on a combination of widgets. Additionally, user model solicitation steps 208 include user interaction with the risk profile and user specification of a target risk level and a perceived importance of interventions on each factor. Further, step 210 includes re-ranking action plans based on the user-specified importance level.
Accordingly, a user identifies important risks and factors for wellness decisions and the system of one or more embodiments of the invention configures the decision service to invoke suitable action plans. The system selects the action plans that have interventions on matching risk factors to those in the solicited user model (that is, the perceived importance levels of the factors and interventions), and the system ranks these selected action plans based on, for example, simplified additive multi-attribute value functions, using either one of the following two strategies.
One strategy includes an information-based rating, which includes ranking action plans with respect to the user model. For example, the importance level of an action plan is the weighted average of factor importance:
$imp (u_{a}, {ap}_{t}) = \sum_{f_{i} \in {ap}_{t}} w_{f_{i}}^{'} imp (u_{a}, f_{i})$ $w_{f_{i}}^{'} = w_{f_{i}} \div \sum_{i = 1}^{n} w_{f_{i}}$
Another strategy includes collaborative rating, which includes ranking action plans with respect to the models of users in the same risk group. For example, the importance level of a factor is determined by the average of importance ratings reweighted by the similarity to the user:
$imp (u_{a}, f_{i}) = \frac{\sum_{n \in N} sim (u_{a}, u_{n}) imp (u_{n}, f_{i})}{\sum_{n \in N} sim (u_{a}, u_{n})}$
FIG. 3 is a diagram illustrating a user model acquisition module and personalization framework, according to an embodiment of the present invention. By way of illustration, FIG. 3 depicts a device 302, a personal wellness record 304, a personalization module 306 which includes a risk stratification component 308, a personal wellness status assessment component 310, a wellness management model 312 and a user model 314. FIG. 3 also depicts a user model acquisition component 316, an intervention component 318 and additional information components 320 (for example, physical activity, nutrition, medication taking, etc.).
As illustrated in FIG. 3, a user can identify the perceived importance to wellness decisions, (for example, with respect to fat, carbohydrate, protein, cholesterol, fiber, etc. intake) as detailed in one of the examples described herein. Accordingly, as depicted in FIG. 3, the personalization engine can select the relevant attributes from a user model to make a prediction of the user's wellness status as well as make follow-up recommendations. If there are some attributes missing from the user model that are essential for prediction and recommendation, the engine will solicit those attributes from the user.
FIG. 4 is a diagram illustrating an example system design for risk-driven wellness decision, according to an embodiment of the present invention. By way of illustration, FIG. 4 depicts a personal wellness decision support (PWDS) application kit 402, a data preparation component 404, a model application component 406, and component 408 which includes a personal wellness decision manager component 410, PWDS manager user interface (UI) 412 and a knowledge manager component 414. FIG. 4 also depicts a scalable platform 416, which includes a PWDS component 418, a user-specified configuration component 420, a configure-free module 422, an expert-provided guideline component 424, a connection 426 to monitoring devices, a connection 428 to clinical experience, a user model 430 and a personal wellness record 432.
In connection with the personal wellness decision support (PWDS) manager 412, when the user knows what to choose, the flow of data can continue to user configuration. When the user does not know what to choose, the configure-free module can be triggered as follows. A dashboard of risk profiles and widgets is provided to display impacts of interventions. Also, feedback is solicited from user to construct user models (that is, target risk and the perceived benefits of interventions on different risk factors). As such, risk action plans are selected based on an information-based/collaborative filtering strategy. Additionally, one or more embodiments of the invention can include an auto scale-in/scale-out mechanism implemented to determine how many instances are needed for current personalization task.
FIG. 5 is a chart illustrating system-level components, according to an embodiment of the present invention. By way of illustration, FIG. 5 depicts a model creation portion 502 and a decision management and sharing portion 504. FIG. 5 describes who the likely users of each component are. For example, a user can use the manager to learn his or her health risk and select follow-up action plans accordingly, using the dynamically generated widget and feedbacks on different interventions. The expert can use PWDS to create or upload new risk models. Also, the vendor can subscribe to different models the experts have created and stored in the knowledge repository. Additionally, the vendor can consequently generate new wellness-related services for target users based on these learned models.
An example of applying risk-driven personalization on the selection of proper nutrition intake plans for diabetic users can include the following (for illustration purposes). Jane, a diabetic patient, has been using a wellness management portal to manage her disease. Her physical examination center has just notified her that her annual check-up report is now ready online. She logged-in to see the report and discovered some problem areas and likely complications (such as, for instance, hypoglycemia episodes) in the physician's note. As she wants to understand a bit more, she enters the risk profiling section.
Accordingly, one or more embodiments of the invention can go through her personal wellness history (including the new physical exam results) to extract features that are related to the problem areas diagnosed by the physician. Also, the system analyzes the risk level of the problem areas using the extracted features and shows a chart to the user that illustrates the problem areas, links each of the problem areas to its likely sources of problem and calculates the importance level of each factor.
Additionally, the user's risk profile can be used to trigger suggestions of follow-up disease management and lifestyle interventions (for example, daily nutrition intake composition) based on national guidelines (or the guidelines prescribed by the physician). In this example case, the user has a high risk of dyslipidemia (specifically, hyper-lipidemia), therefore a special diet intervention is recommended to lower total cholesterol (TC) and LDL cholesterol (LDL-C) concentrations. The national guideline suggests the daily nutrition composition under such risk as follows: fat ≦30%; carbohydrate 50-60%; protein 10-20%; total cholesterol ≦300 mg; fiber 25-35 mg. Going through Jane's blood glucose (BG) monitoring records, one or more embodiments of the invention can also find that the low-fat, high-carb meals are not helping Jane prevent hypoglycemia episodes.
Following up on the requirement of the guidelines, there are several options of diet planning available that can meet the requirement. The configuration-free module of one or more embodiments of the invention can then be invoked to learn the dietitian's opinions on Jane's conditions and Jane's own preferences. First, the acquisition module is invoked to learn the dietitian's opinions on Jane's conditions and Jane's own preferences. She chooses the coronary heart disease (CHD) risk as the target outcome to be improved and uses the dashboard and widgets to visualize what interventions can help reduce the risk. After interacting with the system, she answers questions of the benefits of the different interventions.

One or more embodiments of the invention can then score the action plans with respect to the solicited user model (that is, the perceived importance levels of the factors and interventions).

Fiber	High 0.3	Med 1.0	Low 0.4

For each adaptation (modification and insertion) the adjustment module applies, the system will check if the adapted plan is feasible. Once all of the available diet plans are adjusted, the ranker module can be invoked to score the multiple adjusted plans so that these plans can be displayed in the order of preference. One or more embodiments of the invention can rank these selected action plans based on a simplified additive multi-attribute value function, such as the information-based rating described herein.

Meal Plan 3	0.3	0.5	0.1	0.1	0.4	0.304

Based on the personal nutrition need and preferences, when dining out, the smart nutrition system will personalize the recommendation scoring of each dish on the menu. For example, foods that come with higher proportion of non-starchy vegetables and low-carb fruits (such as berries) will be scored higher for Jane. In addition, one or more embodiments of the invention also receive feedbacks from Jane and use the feedback to update recommendations. The information-based strategy is combined with the collaborative filtering that can learn from a control group.
When system developers know what disease risk models and comorbidity index to incorporate into a user's wellness decision support, they can, for example, use a knowledge manager component to check in the wellness knowledge repository of pertinent risk models, and use the configuration interface of wellness decision services to apply the pertinent risk models on incoming user data.
When system developers do not know what to incorporate, they can invoke the configure-free module, as detailed herein, to learn user models. Developers can then configure the decision services with the learned pertinent risk models and importance risk factors.
Accordingly, the configured wellness decision service can be deployed to users in situations, such as, for example, each time a new user comes in, his/her wellness profile will be created, and when s/he returns the next time, his/her profile will be updated with the changes of risk factors identified through monitoring data.
One or more embodiments of the invention also include a simplified additive multi-attribute value function with collaborative filtering. This provides a workable means to implement the principles of risk-based personalized decision support. Also, it can be more accurate than guideline-based decision support (more realistic scores, tradeoffs, etc.), and can identify interventions, specify perceived benefits over interventions, identify alternative action plans available and measure scores, as well as provide a simple calculation by additive functions and collaborative filtering algorithms.
Accordingly, as detailed herein, one or more embodiments of the invention can provide a personal wellness status assessment (using the past to infer current status). Given the selected risk models from the repository, the system can profile the current wellness status of a user given his/her wellness record. Additionally, one or more embodiments can provide personalized lifestyle intervention recommendations (understanding current status and context). Given the selected risk models and lifestyle intervention plan, the system can trigger the suitable follow-up actions based on wellness records.
Dynamic service delivery (understanding changes) can also be provided, in that given the changes in the wellness record, the wellness decision support can update the user wellness profile accordingly. Further, one or more embodiments of the invention additionally include micropayment provisioning (understanding contribution). As the knowledge manager logs how the risk models and plans are used by other services, the system can help develop a micro-payment provisioning mechanism.
FIG. 6 is a flow diagram illustrating techniques for providing one or more user-centric wellness decision support services, according to an embodiment of the present invention. Step 602 includes providing an interface that facilitates selection of a risk assessment model of interest for a user and an action plan to trigger one or more follow-up action items. This step can be carried out, for example, using a personal wellness decision configuration interface. Providing an interface further facilitates selection of a target population group with which to compare a personal risk level.
In one or more embodiments of the invention, selection of the risk assessment model can be carried out by the healthcare professional (or, for example, a case managers or the user) who work with the service vendors to select the risk assessment model. The user can play with the widget (provided by one or more embodiments of the invention) to understand the consequence of different interventions on the various types of risks being analyzed. Accordingly, one or more embodiments of the invention provide flexibility of model selection on the vendor side, as well as the benefit for the users to select intervention plans based on both health-professional prescribed assessment model and their own preferences.
Step 604 includes applying the selected model to assess the user's wellness risk level based on one or more user wellness records. This step can be carried out, for example, using a risk stratification engine.
Step 606 includes applying the selected action plan to trigger one or more relevant disease management and lifestyle interventions. This step can be carried out, for example, using a personalized recommendation engine. Applying the selected model to assess the user's wellness risk level based on one or more user wellness records further includes assessing the user's wellness risk level based on records from the selected target population group.
The techniques depicted in FIG. 6 also include using a personal wellness knowledge manager to maintain a wellness knowledge repository. The knowledge repository can be used in connection with the models that describe what user attributes are to be used in analyzing a particular type of risk and in what fashion (for example, weighting). One or more embodiments of the invention can also include using a personal wellness decision support client to facilitate sharing of disease management and lifestyle intervention action plans (for example, rules for exercise therapy or nutrition intakes) in an online knowledge repository. Also, a wellness decision service deployment module can be used to analyze input from a knowledge repository (for example, an input disease management plan or related guidelines) and one or more restrictions and constraints in a user risk profile, and output an adjusted plan.
The techniques depicted in FIG. 6 also include providing a configuration-free module for use if there is no user selection of a risk assessment model of interest and an action plan. The configuration-free module solicits input from one or more healthcare professionals and one or more users. Also, the configuration-free module includes an automatic profiling module that constructs a user's wellness profile by scanning through one or more user wellness records and identifying one or more risk factors. Additionally, the configuration-free module includes a user model solicitation interface that facilitates interaction with the user for input of one or more wellness management goals and risk factor importance. Further, the configuration-free module includes a configuration facilitation module that identifies one or more pertinent risk models and associated risk factors and ranks one or more relevant action plans.
Ranking relevant action plans can include information-based filtering by matchmaking a description of each action plan to one or more user records and aggregating an importance level rating of one or more involved risk factors (for example, via:
$imp (u_{a}, {ap}_{t}) = \sum_{f_{i} \in {ap}_{t}} w_{f_{i}}^{'} imp (u_{a}, f_{i}) w_{f_{i}}^{'} = w_{f_{i}} \div \sum_{i = 1}^{n} w_{f_{i}}) .$
Also, ranking relevant action plans can include collaborative filtering by aggregating an importance level rating of each risk factor from one or more users who have a similar wellness history to the user in question (for example, via:
$imp (u_{a}, f_{i}) = \frac{\sum_{n \in N} sim (u_{a}, u_{n}) imp (u_{n}, f_{i})}{\sum_{n \in N} sim (u_{a}, u_{n})}) .$
Additionally, one or more embodiments of the invention include using a wellness decision service deployment module to analyze input from a knowledge repository (for example, an input disease management plan or related guidelines) and one or more restrictions and constraints in a user risk profile, and output an adjusted plan. Further, the techniques depicted in FIG. 6 can include facilitating a vendor to subscribe to one or more models (created by experts) stored in a knowledge repository and new wellness-related services for target users based on the learned models.
The techniques depicted in FIG. 6 can also, as described herein, include providing a system, wherein the system includes distinct software modules, each of the distinct software modules being embodied on a tangible computer-readable recordable storage medium. All the modules (or any subset thereof) can be on the same medium, or each can be on a different medium, for example. The modules can include any or all of the components shown in the figures. In one or more embodiments, the modules include a personal wellness decision configuration interface module, a risk stratification engine module and a personalized recommendation engine module that can run, for example on one or more hardware processors. The method steps can then be carried out using the distinct software modules of the system, as described above, executing on the one or more hardware processors. Further, a computer program product can include a tangible computer-readable recordable storage medium with code adapted to be executed to carry out one or more method steps described herein, including the provision of the system with the distinct software modules.
Additionally, the techniques depicted in FIG. 6 can be implemented via a computer program product that can include computer useable program code that is stored in a computer readable storage medium in a data processing system, and wherein the computer useable program code was downloaded over a network from a remote data processing system. Also, in one or more embodiments of the invention, the computer program product can include computer useable program code that is stored in a computer readable storage medium in a server data processing system, and wherein the computer useable program code are downloaded over a network to a remote data processing system for use in a computer readable storage medium with the remote system.
Further, in one or more embodiments of the invention, the techniques depicted in FIG. 6 can be implemented via instantiation of program code in a system engine, where the description can be translated into a computable program to make inference from the input data.
